Question
1. What is meant by the term oxidation?
a. The loss of electrons by the compounds in chemical reactions.
b. The gain of electrons by the compounds in chemical reactions.
c. The combining of elements with O in chemical reactions.
2. On which side of an oxidation half-reaction do the electrons appear?
3. What is meant by the term oxidant?
4. What is meant by the term oxidizing agent?
c. It is oxygen in any oxidation reactions.
d. The compound which reacts with oxygen in the redox reaction
a. On the left side (reactants). b. On the right side (products).Explanation / Answer
1. The term oxidation means "loss of electrons", so choice (a).
2. Electrons appear on the products side of a half reaction, so choice (b). For example:
Fe --> Fe2+ + 2e-
3. An oxidant (or oxidizing agent) is a chemical species which performs oxidation on another chemical. The is, the oxidant gets reduced. Often times, this is oxygen in a reaction. Thus choice (b)
4. Since the oxidizing agent gets reduced, it is gaining electrons. Thus the answer is choice (b).
